So I bought a house (woot)

It had a little mold (booo)

The inspector stated it was 3 or 4 days at $1K/day to clean it up....this was minor mold in expected areas.... near bathroom shower and a leak under the kitchen sink, some condensation near the HVAC....this wasn't a big deal...

So I go online....figuing bleach is the way to kill this stuff. Ech, long story, guess not....I guess it tends to react atthe surface only and not get deep enough to deal with the stuff so it reappears.

Enter Concrobium...which seemed to be the solution. fine, great, I bought a gallon and treated the problem and we'll see if it works. Reading the label, it's .95% Sodium Carbonate (Soda Ash) and "Inert Ingredients"....WTF, why's it $35 bucks?

So I read up....found a post by a guy claiming to be from the company that said it's this, water and "2 other ingredients"...and references a non-organic water soluable polymer. In Canada, they claim the active ingredient is simply trisodiumphospate (TSP).

So I pull the patent

and with putting the puzzle pieces together, here's a generic, make it yourself version:

1% or so Sodium Carbonate
.5% sodium bicarbonate (or sodium biphosphate)
.5% Trisodium Phosphate
Balance is water.

So, to a gallon of warm water (to help disolve the salts):

2 1/2 tablespoons Sodium Carbonate
4 teaspoons Sodium Bicarbonate
4 teaspoons TSP

Sodium Carbonate is available as pool supply (ph Up or Increaser) or photography places. I saw it fot $15 for 5 pounds...which would make a ton of your knockoff mold killer.

Sodium Bicarbonate is BAKING SODA! (Also as pool supply as Alk-UP or 'Alkalinity Increaser') Maybe a buck?
TSP is $2.50 a pound.

I don't claim this is the formula, just ballparking it....and all you really need is the Sodium Carbonate to do the job.

The polymer is probably 2% of something like Aqualon cellulose gum in food grade, but not required to make this work. Guess it helps keep foaming down and the salts suspended. Organic polymers like guar or triagacanth would probably work fine to. [url=http://www.herc.com/aqualon/]

Spraying some Concrobium on glass and letting it dry, yep, looks like a polymer in there, lol....

So, for the cost of 1/2 gallon of the commercial product you can make enough to do the whole block.

At your own risk, don't try this at home, etc. I coould be dead wrong. Smile
